This is the first example of a new species, codex Sinaiticu, from the ancient Greek codex and is the oldest of its kind.
Its discovery is an important first step in establishing whether a modern species is actually extant.
“It’s the first of its genus to be found,” said Dr Nick Balfour, who led the study at the Natural History Museum in London.
“We know the species is a species but its exact genetic history is unknown.”
It has no eyelids, only a very slight chin and no eyes.
The researchers analysed the jawbones and teeth of two codex fragments from the Greek city of Mycenae, in which they discovered the species.
“There was nothing about it that was unusual or unusual about it at all,” said co-author Dr Tim Leake.
“Its jaws were all square and symmetrical, the teeth were flat, the mouth was smooth and its skull was rounded.”
The researchers identified the species by using genetic techniques to look at the fossilised bones of codex fragment SINAITICUS, from Mycena.
The new species is the only one that had a head.
The team also compared the skull of the species with a specimen from the early Paleolithic period, which had been unearthed from the site of an ancient Bronze Age site near modern-day Hungary.
The findings, published in the Journal of Vertebrate Paleontology, are important for establishing whether the new species actually exists.
The first known specimens of codices were found in the early Bronze Age at Mycene in Greece, but the site has long since been submerged.
“Sinaiticum has an amazing amount of information to offer us, as well as showing how it might have looked like,” said lead author Dr Leake, from Newcastle University.
“You can actually make out a lot of details about the way the teeth look, the shape of the jaw and even how the skull was laid down, which is an indication of its evolutionary history.”
Ancient codex The first codex was found in an archaeological site called Paphos in Greece.
Its teeth were so similar to modern species that it was thought to be a direct copy of modern species.
But the ancient codex did not match the modern species, and so the scientists used a technique called morphological dating to date it.
This allows researchers to estimate the age of ancient fossils based on the morphology of their bones.
“When we use morphological dates, we can make the assumption that the specimen was created between 100 and 1,000 years ago,” said Professor Stephen Ritchie from the University of Newcastle.
“And that is not the case for this specimen.”
This is because the skull in this sample had been so badly damaged that it showed signs of being in bad shape from the time it was deposited.
“This is an incredible example of how we can estimate the size of the ancient specimen based on an analysis of its teeth,” said Balfours co-researcher, Professor Mark Leake of the University’s School of Earth and Environmental Sciences.
The newly discovered species is about 2.5 metres long, and weighs between 3.3 and 3.6 tonnes.
The teeth on the new specimen are much bigger than the previous specimen, indicating it is much bigger and stronger than the original codex.
It is also more robust than modern species of codx, because the team found that the bones of the skull were strong and durable.
“The bones are of a good quality, and the material is not too fragile,” said Leake in a press release.
The codex is about 200 million years old, and was probably buried by a lake in the city of Ephesus.
“What’s really exciting about this is that we know it’s a new codex, and that it’s not a very well-known species,” said Prof Ritchie.
The new codices could help scientists better understand how the animals lived in the ancient world. “
These are not the same species as we have ever found before.”
The new codices could help scientists better understand how the animals lived in the ancient world.
The ancient codices also provide a glimpse into the evolution of many of the modern animals.
“One of the interesting things about this discovery is that the morphology is a little different from what we expect from modern animals,” said Ritchie in the press release, “and that’s an important clue for how the ancient animals evolved.”
“This new species has very little or no teeth.
Its jaw is square and has a slightly rounded tip.
Its mouth is also rounded and has no teeth at all.
This makes it a pretty easy specimen to use to get to know the morphology and behaviour of the animals it represents.”
The findings have a big impact on how scientists view the ancient species, since
